Bios used was shipping bios, which seemed to be newer than the one offered on DFis own website. After I flashed to the bios on the DFI page, the Vdroop control feature was gone, so I re-flashed the other bios (09 something).
Might want to try another BIOS. 10/07 I used for the screenshots doesn't appear to have the issue. I do have VDROOP set to "Disabled" but that was a mistake on my part. I was doing some other testing and forgot to change it back to "Enabled" when I did those benches.

I now have the 10/30 BIOS loaded and VCORE is fine with it when both EIST and C1E are "Enabled" regardless of VDROOP setting.
